Cook the aromatics. Melt butter in a Dutch oven, or a large saucepan with a lid. Add onions and cook over medium heat for about 3 minutes, or until soft. Add garlic and continue to cook until fragrant; about 20 seconds. Stir in the smoked paprika.
Add the vegetables and broth. Stir in green beans, tomatoes, and season with salt and pepper. Add vegetable broth, give it a good stir, and bring to a boil.
Cook. Reduce heat to LOW and cover with a lid; continue to cook for 1 hour, or until green beans are very tender.
Season and serve. Taste for seasonings and adjust accordingly. Serve immediately.
